I always get confused on this.

I heard it was any car up to a 93 didnt need a cats so only the early 93s got through with not needing a cat.

Then I head anything older than 10 years doesnt need a cat

Then also been told if it came out factory with a cat it must have a cat on it

Top Gear says: If your car was fitted after 1st August 1992 with a catalytic converter from new, you need to have one for the MoT.

However, the following information was in MOT Tester Magazine:

q) Your vehicle has had its catalytic converter removed and replaced by a normal exhaust silencer but passes the emissions Test. Does it fail the MOT because it hasn't got a catalytic converter when it should have one?

a) No, if it passes the emissions part of the MOT that is acceptable.

There are some variations to the rule and some loopholes as well.

Cats and MOTs !!!!!

There is no part of the MOT test to see if a cat is fitted to a car or not - having no cat is not a failure in itself (how do you tell if the uppipe has been changed for example).

However the car will still have to pass the emissions test at the same values as if a cat was fitted.

Therfore no cat = no failure as long as emissions passed

However (to muddy the water somewhat) the MOT emissions test requires THE EXACT MODEL to be entered onto the computer for the emissions test. Early imports (i think up to about MY95) are not listed - WRX/STi etc. Therefore the car would be required to pass the idle emission test only. ie not the full cat test as there is no database listing for the emissions required for these cars
